Your phone should allow you in to the MyO2 app when on mobile data without logging in.
For phone issue, check this guide Guide: Is the network down for me or everyone?
I have no affiliation whatsoever with O2 or any subsidiary companies. Comments posted are entirely of my own opinion. This is not Customer Service so we are unable to help with account specific issues.
